Are your f5 administrators aware of the "roles" feature that allows administrators such as yourself to access the systems in read-only mode?
The roles include:
Administrator - Complete access to all objects and configuration synchronization on redundant system pairs.
Manager - Create, modify and delete virtual servers, pools, pool members, nodes, custom profiles, custom monitors and iRules(tm); view all objects.
Application Editor - Modify nodes, pools, members and monitors; view all objects.
Application Security Policy Editor - Complete control of the Application Security Manager; view all objects (analogous to administrator for BigIP systems with ASM installed).
Operator - Enable and disable nodes and pool members; view all objects.
Guest - View all objects.
In the meantime, if your f5 administrator is comfortable with it, they could send you the bigip.conf itself, it's one way to read it (which is only okay if you're comfortable reading command line config and stitching it together) or they could take screen shots and send it to you.
There might be another clever way to provide the same info.. I'll give it more thought or maybe someone else will chime in too. But as a regular and ongoing basis, I think having an role setup for you is essential.
